On Jan. 25, 2012 Apple‘s stock-market value jumped to $416.5 billion, according to FactSet, giving it a slight edge over Exxon Mobil as the most valuable company in the world. Not only has the tech behemoth held that lead ever since, but the gap widened to as much as $240 billion in September when Apple was hitting record highs.

That gap alone is greater than the value of some 98% of the companies in the S&P 500.

Over the summer Apple even gained the title of biggest U.S. company of all-time, surpassing Microsoft‘s previous peak in 1999.

But Apple’s fall in recent month has been fast and furious. Thursday alone, the company’s market cap fell by as much as $59.48 billion, according to WSJ Market Data Group. At one point, the gap between Apple and Exxon’s market cap had narrowed to only about $6.2 billion.

Early this afternoon, Apple had a market cap of $431.1 billion, while Exxon’s value was $417.1 million, FactSet data show.
